To all whom itma z concern Be itknown that I, JOH J. DUTROW, a citizenof the United States, residing at Westminsten in the county of Carrolland State of Maryland, have invented certain new andv usefulImprovements in Attachments for Potato-Planters, of which the followingis a specification.

This invention relates toattachments for potato planters, and one of theprincipal objects of the invention is to provide reliable and efficientmeans for moving the covering disks laterally and for tilting the diskat the required angle to overcome the various conditions incoveringpotatoes.

Anotherobject of the invention is to provide a sliding bar on which thecovering disks are mounted, said bar being pivoted totilt at anyrequired angle, and means being connected to said bar to slide the samelaterally for throwing dirt over the potatoes as they are droppedthrough the discharge boot.

These and other objects may be attained by means of the constructionillustrated in g the accompanying drawings, in which:

Figure l is a view in rear elevation of an attachment for potatoplanters made in accordance with this invention, Fig. 2 is a view inelevation of the lever and connecting'means for sliding the bar carryingthe disk coverers, Fig. 3 is an enlarged elevation of the pivoted guidefor the coverer bar and the spring bolt for holding the guide inadjusted position, Fig. A is a side elevation of the same, Fig. 5 is aview in elevation of the gearing for sliding the coverer bar, and Fig. 6is a detail plan view of a brace pivotally connected to the coverer barat one end and at its opposite end connected yieldingly to a frame braceor bar.

Referring to the drawings, the numeral 1 designates the axle and 2 arethe traction wheels of an ordinary potato planter of the usual or anysuitable construction. The discharge boot 3 which receives the potatoesfrom a hopper, (not shown), drops the potatoes in the center between thecovering disks. The covering disks i are connected to a sliding bar 5,said bar extending through a guide consisting of spaced members 6 havingrectangular openings 7 therein to receive the bar 5.

Connected integrally with the spaced guide members 6, is an arm 11, andthis arm 11 is held connected to the boot 3 by means of a, p in 8which-extends throughthe arm 11 and through; a, sector rack-9. Thesectorrack 9 is secured, rigidly. to the boot 8 in;

any suitable manner,'as by a rivet 0 shown in dotted lines in Fig.3,.and by; means of the pin 8 The sector; rack Q is, provided withaseries of'notcheslO. Projecting from the arm 11 are lugs 12, andmounted to move in registered openings in said lugs 12 is a sliding'bolt13 to which a spiral spring 14 is connected at, one endand disposed between the lugs 12,. said spring surrounding the shank of the bolt 13.,Th tension of the spring; 14 is exerted tonorrnally hold the squaredjend15 0f the bolt in engagement Withone ofthe notches 10in the sector rack9; At the top of the bolt 18 is a ring (Z, which may be grasped by thedriver for lifting the'bolt out of the notches 10 when it is desired toswing the covering disk up or down, one relatively to the other.

Connected to the sliding bar 5 is a plate 16 and engaging an eye in saidplate is a connecting rod 17, said rod being upwardly curved at 17 andattached at its opposite end to a lever 18, having an angular arm 19, onwhich is mounted a fixed mutilated gear 20. The angular member 19 issupported upon a bar 21 by means of a strap or keeper 22. A mutilatedgear wheel 23 mounted on a shaft 24 is permanently meshed with the teethof the gear 20, and connected to the gear 28 is a lever 25 provided witha spring bolt adapted to engage the teeth of a rack 26. Connected to alug 27 upon the rear side of the boot 3 are diverging brace members 28and connected to one of said brace members is an angular bracket 29. Thebraces 28 are supported on the frame of the machine in front of theaxle 1. A brace 30 is pivoted'in a strap 31 connected to the coverer bar5, the pivot pin 32 extending through the strap and bar, and the brace30 being connected at its opposite end by means of a bolt 33 extendingthrough the two members of the bracket 29. A spring 3A surrounds thebolt 33 and bears at one end against the brace 30 and serving to holdthe brace 80 yieldingly to compensate for the movements of the bar 5,said bar beingv 25 to move the bar 5 in the guide member 6 to eitherside of the discharge boot 3. Whenever, for any reason, it is deemednecessary to tip the bar 5 carrying the disks 4, this may beaccomplished by moving the arm 11 to one side or the other by pullingupward on the ring 03 to lift the lug 15 from one of the notches 10 inthe rack 9 and then moving the arm 11 to the desired notch. When it isdesired to hold the sliding bar 5 in a horizontal position the bolt andarm 11 is moved to the central notch in the rack 9.

From the foregoing it will be obvious that an attachment for potatoplanters made in accordance with this invention is comparatively simplein construction, can be readily attached to any standard make of potatoplanter, and that the coverer disks can be quickly moved laterally withrelation to the discharge boot and that the'disks may also be tilted atany required angle, thus operative efficiently under varying conditionsupon irregular surfaces of the ground.

Various changes in the details of construction may be resorted towithout departing from the spirit and scope of the invention as definedin the claims.

What is claimed is:

1. An attachment for potato planters comprising a discharge boot, aguide pivoted to said boot, a bar slidably mounted in said guide, disksconnected to said bar, and means whereby said bar may be moved laterallyin said guide, and means whereby said bar may be tipped upon its pivotalpoint.

2. An attachment for potato planters comprising a boot, a guide pivotedto the boot, a bar mounted to slide in the guide, disks connected tosaid bar, a lever and connections for sliding said bar in said guide, arack, and a spring bolt for holding the bar at any required angle.

In testimony whereof I aiiiX my signature in presence of two witnesses.
